bluez

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I am trying to write an application which searches Bluetooth devices nearby and communicates with them. My application is going to be written in C++, and intended to work under Linux. 4 years ago, I used BlueZ. But now, as I see, the API has been changed a lot and now it's using D-Bus. I was not experienced with

问题 I am trying to connect to a Raspberry Pi via iPhone using CoreBluetooth (bluetooth 4.0). I have discovered the device and send out a connection request using this code: if (peripheral != self.foundPeripheral) { NSLog(@"Try to connect to %@", peripheral.name); self.foundPeripheral = peripheral; [self.centralManager stopScan]; [self.centralManager connectPeripheral:peripheral options:nil]; } Neither the didConnectPeripheral or didFailedToConnectPeripheral are called. I also made sure to set the

问题 I'm trying to connect to a BLE device (Heart rate sensor, Polar H7), on a Raspberry Pi 2. I use the last version of bluez (5.35) found here: http://www.bluez.org/download/ But when I'm trying to connect using gatttool , I always have "connection refused" error. Here is what I do : pi@raspberrypi ~ $ sudo su root@raspberrypi:/home/pi# hciconfig dev hci0: Type: BR/EDR Bus: USB BD Address: 5C:F3:70:69:54:3D ACL MTU: 1021:8 SCO MTU: 64:1 DOWN RX bytes:616 acl:0 sco:0 events:34 errors:0 TX bytes

问题 Goal I am developping a simple device running Linux. It is BLE capable, and I am currently using bluez 5.8. I want to trigger an action on this device using an iPhone. What already works: I can make the iPhone "see" the device. The iPhone also connects to the device. I setup the bluetooth device like this on linux (thanks to this question): # activate bluetooth hciconfig hci0 up # set advertise data: "hello world" hcitool -i hci0 cmd 0x08 0x0008 48 45 4c 4c 4f 57 4f 52 4c 44 # start

问题 I would like to know if there is a way to set up a gatt server from the Linux command line. I know that the BlueZ gatttool command allows you to act as a gatt client and interrogate a remote gatt server, however, I do not think that this tool can be used to set up a server. What I want to achieve is a gatt server, created from the command line , and can be interrogated by any central device (e.g. iOS or Android device) to connect to the GATT server, discover the services and characteristics,

问题 Using BlueZ-5.43, Nordic nRF52832 and Raspberry Pi Raspbian. I can create an l2cap socket and perform service discovery and attribute read and write operations on characteristics. However, this solution by-passes creating a connection via the HCI and subsequently uses defaults for parameters such as supervision timeout and slave latency. Going through hci.c using hci_le_create_conn allows me to override these defaults, but I get a handle number 64 with no obvious means to use this handle for

问题 I am trying to configure a bluetooth chip for linux to pair with an android phone. I will have a display on which I am able to show a 6 digit passkey, so I am trying to set the Bluetoothctl agent to DisplayOnly. According to the table in this post https://www.silabs.com/community/wireless/bluetooth/knowledge-base.entry.html/2016/07/11/bt121_-_legacy_pairi-MnCo If the responder is DisplayOnly, and the initiator (Android) is KeyboardDisplay, it should use Passkey entry, with the responder

问题 I'm implementing OOB Pairing between iOS 10 device (iPhone) and embedded Linux device (3.10 kernel version, 5.35 BlueZ version) via USB (iAP2 protocol, CarPlay). My question is: does BlueZ supports this kind of pairing? Where to find some information on that? What I have now: OBB Pairing working flawlessly from the iOS side (e.g. after USB connection established for the first time, I have my Linux device in "My Devices" bluetooth section of the phone). On Linux accessory's side I'm receiving

问题 Is it possible to make a peripheral scan for advertisments while connected to a central? It seems like it is either scanning for advertisments or have your peripheral connected but I need to do both. The peripheral should be able to report RSSI measurements from advertisements it picks up. I'm using 'bleno' for the peripheral and 'noble' for the scanning on a linux box (bluez) 回答1: The answer to this differs depending on the version of Bluetooth that your device is on. For Bluetooth v4.0: A
